Question

Suppose we conduct an experiment to demonstrate respiration in a green plant. What special precaution is required to be taken in it?

Answer 1

The plants should be placed in dark room or it should be covered.
because rate of photosynthesis is higher than respiration in normal light. So, carbon dioxide produced by respiration will be utilized for photosynthesis. And we can't detect carbon dioxide. Therefore photosynthesis has to be stopped so we keep plants in darkness.
